1 Claim.

This invention relates to a pin and pertains more particularly to anarticle of this kind especially adapted for use in connection withgarments for infants.

It is an object of the invention to provide an article of this kindwhich is readily applied or removed by a rotary action.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved safetypin whereby certain advantages are attained, as will be hereinafter morefully set forth.

In order that my invention may be better understood, I will now proceedto describe the same with reference to the accompanying drawings,wherein:

Figure 1 is a view, in plan, of a pin constructed in accordance with anembodiment of the invention;

Figure 2 is a side elevational view of the device illustrated in Figure1;

Figure 3 is a side elevational view opposite to Figure 2; and

Figure 4 is a sectional view taken substantially on the line 4-4 ofFigure 1.

In the embodiment of the invention as illustrated in the accompanyingdrawings l denotes a circular head or button of desired dimension andwhich may be made of a plastic or other material.

Disposed slightly more than one-half way around the head or button I atthe periphery thereof is a flange 2 extending outwardly from andsubstantially at right angles to the inner face of the head or button.

The outer edge face a of the flange 2 gradually rises or increases inheight in the nature of a helix from the button back face, or from azero height at one end, to a point close to the opposite end thereof.The end portion 1) of the edge face of the flange 2 remote from the lowor zero end thereof terminates in an inclined face having an angle ofapproximately 45.

As shown in Figure 1, the face a of the flange is also of graduallyincreasing width from the low end of the flange to the high end thereof.

Overlying the edge face a of the flange 2 but normally spaced therein ishelical pin 3 which has an end portion anchored as at 4 to the head orbutton at a point immediately adjacent to the outer extremity or base ofthe portion b of the flange 2. As herein disclosed pin 3 has anangularly disposed tail extension, or shank, 5 which is embedded withinthe head or button I The pin 3 extends from its anchorage 4 across thespace between the ends of the flange 2 and continues in overlyingrelation with respect to the flange 2 from the zero end thereof,terminating short of, but relatively close to, the end portion 17 of theflange 2.

It is believed to be obvious that upon rotation of the head or button Iin one direction about its axis, the pin will be carried to penetratethe garment or the like as desired and the inherent resiliency of thepin 3 will allow the pin to serve as a clamping medium coacting with theedge face a of the flange 2 to maintain the applied device in appliedposition. In the initial application of the article, the end portion 1)of the flange 2 will assure the portion of the garment or the like to bepenetrated by the pin 3 to be in the best position for such penetration.

Upon reverse rotation of the head or button, to free the pin 3, thecoaction of the face a and the flange 2 with the material of the garmentor the like will materially facilitate the freeing or withdrawal of thepin 3.

The efliciency of the article is further increased by the fact that theportion of the pin 3 which is opposed to the face a of the flange 2 isnormally equidis-tantly spaced at all points therealong from said facea.

From the foregoing description it is thought to be obvious that a safetypin constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated.

I claim:

An article of the character described comprising a button body having aback face, an arcuate flange rising from said face in the nature of ahelix from a low end to a high end, and a pin having an end secured tosaid face at the said high end of the flange and rising in a helix ofthe same hand as and in spaced relation with the flange, said flange atthe high end thereof having an end face disposed at an angle ofapproximately with respect to the adjacent face of the button body, thesaid secured end of the pin having a shank portion entering and embeddedin the button body at the bottom of said inclined face.
